According to one embodiment of the invention, communication device (such as, communication device 100A or 100B) can pass through to transmit and receive multiple radio frequency signal and a remote-control device (such as, a community of network-side, an eNB, a base station etc.).In an example, for the application that single deck tape-recorder list as shown in Figure 1A is treated, communication device 100A can follow the communications protocol of a correspondence and a remote-control device to carry out communication.In particular, communication device 100A can before being stationed (campon) or an online upper remote-control device, with this remote-control device communication.Communication device 100A also can perform set program, in order to be stationed or online this remote-control device upper, and in being stationed or after online this remote-control device upper, keeping in communication with this remote-control device.It is stationed or whom the program of an online upper remote-control device (such as, a community of network-side, an eNB, a base station etc.) know the program that this those skilled in the art is known for, therefore repeat no more in this.
In another example, for the application of multi-card multi-standby as shown in Figure 1B, each communication unit being contained in communication device 100B can follow the communications protocol of a correspondence to carry out communication with a corresponding remote-control device.In particular, each communication unit that communication device 100B comprises can in being stationed or before one of online upper correspondence remote-control device, with this remote-control device communication.Each communication unit that communication device 100B comprises also can perform set program, in order to be stationed or the remote-control device of online upper correspondence, and in being stationed or after online this remote-control device upper, keeping in communication with this remote-control device.
In being stationed or after the remote-control device of online upper correspondence, communication device (or, corresponding communication unit, will be used below communication device representatively) idle mode can be operated on, and listen to the calling (paging) from network-side.Fig. 3 shows that communication device processes a streaming example of call forwarding message.When one of communication device automatic network end remote-control device receives a call forwarding message 301, communication device can transmit an online request message 302 (such as, by third generation cooperative programme (3rdGenerationPartnershipProject, a 3GPP) defined wireless heterogeneous networks (radioresourcecontrol, RRC) online request message RRCConnectionRequest) to remote-control device, online in order to set up RRC.In response to the online request message 302 received, the remote-control device of network-side can transmit an online message 303 (such as, being set up message RRCConnectionSetup by the wireless heterogeneous networks that 3GPP is defined is online) of setting up to communication device.It is online that communication device can set up RRC, and then response one online foundation completes message 304 (such as, the online foundation of the wireless heterogeneous networks that 3GPP is defined completing message RRCConnectionSetupComplete) to remote-control device.Transmitting after online foundation completes message 304, communication device can leave idle mode and enter online mode.
Fig. 3 shows streaming example when receiving call forwarding message in a cellular network.When the communication device supporting LTE communication is stationed or the eNB of online upper LTE, and receive circuit switching (CS) when calling, need to trigger a circuit switched fallback program (CircuitSwitchFallback, CSFB) program, in order to the old network of rollback to (legacynetwork) (such as, 2G or 3G network).Processor can pass through to inspect core network field (cn-Domain) field contents in calling record, to judge that the call forwarding message received is as circuit switching (CS) calling or packet switch (PacketSwitch, PS) calling.
Fig. 4 shows that communication device processes the flowchart example of CS calling in LTE network.When communication device is from the remote-control device be stationed, for instance the eNB of LTE, receiving during CS call forwarding message (step S402), communication device can perform one and online set up program (step S404), sets up online with remote-control device in order to attempting.In particular, communication device can as it is shown on figure 3, transmit an online request message to remote-control device.
When online set up program success time, such as, communication device as shown in Figure 3 from remote-control device receive one online set up message time, communication device can then transmit an expansion service request (ExtendedServiceRequest, ESR) message is to remote-control device, with initial CSFB program (step S406).During CSFB program, forwarding information (redirectioninformation) can be sent to communication device by remote-control device.In forwarding information, remote-control device may indicate that a target frequency.Then, communication device is movable in the wireless access techniques system of target (such as, 2G or 3G), and uses the suitable community of frequency information search.Selecting (cellselection) program compared to a community, the CSFB with forwarding information can make communication device take less time the community identifying the best.
But, online program of setting up is likely to meeting failure.For example, when after communication device transmission online request message to remote-control device, it is impossible in time receiving any response message with remote-control device, online program of setting up can failure.As defined in 3GPP communication standard TS24.3015.6.1.6, when the failed generation of a lower level, communication device should perform a cell selection procedure, it is used to old network (such as, GSM/EDGE cordless communication network (GSMEDGERadioAccessNetwork, GERAN) or UMTS land access network (UMTSTerrestrialRadioAccessNetwork, UTRAN) suitable community is selected (such as by communication device oneself in, 2G or 3G community), and it is stationed this suitable community.
Fig. 5 shows that 3GPP communication standard TS24.3015.6.1.6 is defined and is processed the flow process example that lower level is failed by communication device.When communication device determines to trigger a CSFB program (step S502), communication device as online in above-mentioned triggering one can set up program, and transmit an online request message to remote-control device (step S504), in order to attempt with remote-control device, to set up one online.Communication device can set up an initial set intervalometer in program in online, for instance, T300 intervalometer.
As defined in 3GPP communication standard, T300 intervalometer in transmit online request message time initiateed, and in receive one online set up message, an online refusal message, one cell reselection instruction message or online foundation stop time be stopped.
In the T300 intervalometer appointed date (namely, timing time to) when and communication device fail when remote-control device receives any response message, communication device should perform a cell selection procedure (step S506), to select GERAN or UTRAN wireless access techniques voluntarily.Therefore, as defined in 3GPP communication standard, communication device only can attempt with set up remote-control device set up online once.If this time attempting failure, communication device has to carry out cell selection procedure and replaces CSFB program.
But, blindly the old network of DIYU (for example, 2G or 3G network) is found suitable community and is likely to fairly time consuming and is likely to result in communication device and camps on the community that signal quality is poor, it is thus possible to increases CS call and sets up mortality.
In order to solve this problem, several efficient wireless communications methods described below.
According to one embodiment of the invention, when determining to trigger a CSFB program, processor is (such as, processor 222) an online request message can be transmitted (such as by transceiver, RRCConnectionRequest) to remote-control device, set up online with remote-control device in order to attempting.Meanwhile, processor also can initiate a set intervalometer, for instance, T300 intervalometer.When the set intervalometer appointed date and communication device fail to receive any response message from remote-control device, such as, online when setting up message (RRCConnectionSetup) or online refusal message (RRCConnectionReject), processor can transmit this online request at least again to remote-control device, set up with remote-control device that this is online in order to reattempt to, above-mentioned behavior defined with 3GPP communication standard TS24.3015.6.1.6 and differ.
Fig. 6 shows the efficient wireless communications method flowchart example according to one embodiment of the invention.When communication device receives CS call forwarding message from the community being stationed (step S602), wherein this community being stationed can be LTEeNB, communication device can perform online as above to set up program (step S604), to attempt setting up online with remote-control device.
Then, processor can confirm that and online sets up program whether success (step S606).Setting up program successfully when online, processor then can transmit an ESR message, to start CSFB program (step S608).
When online procedure failure of setting up, whether processor can confirm that because of the T300 intervalometer appointed date lead to the failure (step S610).If it is not, then processor can determine to perform cell selection procedure described above (step S614).If leading to the failure because of the T300 intervalometer appointed date, processor can determine whether to transmit whether time of spending of online request reaches the maximum trial time or transmit the number of times of online request and whether reach a maximum attempts (step S612).In this, described reach to represent equal or more than.If it is not, processor can determine to return step S604, again transmit online request to remote-control device, set up online in order to reattempt to remote-control device.Parameter Trial_Num system is in order to calculate the number of times that online request is transmitted, and it can be set to 0 when first time enters step S604, and before returning step S604, can be cumulatively added 1 in step S616 every time.Processor also can in return step S604 with perform once again online set up program time, initial set intervalometer once again.
If the time that transmission online request spends has reached the maximum trial time, or the number of times transmitting online request has reached a maximum attempts, then processor can determine to perform cell selection procedure described above (step S614).
According to one embodiment of the invention, processor can determine maximum trial time and maximum attempts according to the experience previously attempted.Processor can start to calculate the time that transmission online request spends when first time enters step S604.
Fig. 7 shows the flow process example failed by communication device process lower level according to one embodiment of the invention.When communication device determines to trigger a CSFB program (step S702), communication device as online in above-mentioned triggering one can set up program, and transmit an online request message to remote-control device (step S704), in order to attempt with remote-control device, to set up one online.Communication device can set up an initial set intervalometer in program in online, for instance, T300 intervalometer.
In the T300 intervalometer appointed date (namely, timing time to) when and communication device cannot when remote-control device receives any response message, communication device can determine that starting one retries program, set up online (step S706) with remote-control device in order to reattempt to, and the online request message that retransfers is to remote-control device (step S708).Communication device also can initiate T300 intervalometer once again.
In the T300 intervalometer appointed date (namely, timing time to) when and communication device still cannot when remote-control device receives any response message, and when transmit time of spending of online request not yet reach the maximum trial time and transmit the number of times of online request not yet reach a maximum attempts time, communication device can transmit online request again to remote-control device (step S710), and initiates T300 intervalometer once again.It should be noted that in embodiments of the invention, in retrying in program, communication device can transmit one or more online request to remote-control device, sets up online to reattempt to remote-control device.
When the number of times that the time that transmission online request spends has reached a maximum trial time or transmission online request reaches a maximum attempts, communication device can determine that stopping retries program, and as above-mentioned, perform a cell selection procedure (step S712).
The behavior defined compared to the 3GPP communication standard shown in Fig. 5, after wherein in first time, online failure is set up in trial, communication device just directly performs cell selection procedure, in embodiments of the invention, communication device can trigger the program of retrying, and again sets up online at least one times with remote-control device with trial.Therefore, when communication device is only temporarily be in the region that signal quality is not good, or because of some reason remote-control device temporarily cannot receive online request message maybe cannot transmit a response message time, by implementing above-mentioned method, can in retry program is successfully established online.Therefore, in embodiments of the invention, owing to CSFB program can be triggered after retrying program success, can avoid performing relatively time consuming cell selection procedure thus, and communication device also successfully can obtain forwarding information from remote-control device.
The above embodiment of the present invention can perform in many ways, for instance uses hardware, software or its combination to perform.Those who are familiar with this art should be appreciated that the set of any assembly or assembly that perform above-mentioned functions can be considered the processor of one or more control above-mentioned functions.These one or more processors can perform in many ways, for instance by specifying hardware, or the common hardware that use microcode or software program is to perform above-mentioned functions.
Although the present invention is disclosed above with preferred embodiment; so it is not limited to the present invention, any those who are familiar with this art, without departing from the spirit and scope of the invention; when a little change and retouching can be done, therefore the protection domain of the present invention when depending on after attached as defined in claim be as the criterion.
